Shared components (multiple parents)

Question

Hi,
I have posted a question in the AWT section, but it relates to Swing too, so I'm posting a link here. Please take a look:

Thanks.

I just gave you an example.
You have a "Cancel" button that you add to multiple
non-modal dialogs that can all be open at the same
time (different tool palettes for example). You write
a generic ActionListener so then when the button is
clicked, you close the dialog containing the button.
So the generic code simply invokes the
SwingUtilities.windowForComponent(...) to get the
window so it can close the window. But it can't find
the single parent because that relationship no longer
exists.Sorry, but I still don't understand what would stop multiparented version of Swing from invoking SwingUtilities.windowsForComponent(...) to get the array of windows so it can close every one of them. If I insert the same Cancel button into multiple dialogs, I have to know what I'm doing and be prepared for this behaviour.
So, basically using your approach you lose the
ability to write generice code and classes of this
nature.I can still have one parent, but I can also have multiple (and deal with the consequences, of course).
I really don't understand what you are trying to do,
because Swing won't allow you to do this anyway. Are
you planning on rewritting Swing? Have fun.No, that would be too much fun for me :) I'm just writing a simple GUI kit for mobiles, because the one in MIDP doesn't do much, and I was curious about this restriction.
